IMPROVEMENT IN APPARATUS FOR TRANSMITTING MOTION.

Specification forming part of Letters Patent No. 154,008, dated August11, 1874; application led July 6, 1874.

To all whom it may concern:

Beit known that I, LEVr BINGAMAN, of Coventryvillc, in the county ofChester and State of Pennsylvania, have invented an Improved Apparatusfor Transmitting Motion, of which the following is a specification:

My invention consists in, first, the combination of reciprocating beamsconnected by cords or chains, for the purpose of receiving andtransmitting motion; second, the combination with the reciprocatingbeams of two rotating shafts, one for transmitting motion to the beamsand the other for receiving mo tion therefrom 5 third, the combinationof a spindle, cord, and shaft, for adjusting to a proper degree oftension the cords or chains which connect the beams; fourth, thecombination of weights, cords, and arbors, for automatically tighteningthe cords or chains when necessary.

In the accompanying drawing, Figure l is a side view of my improvedapparatus. Fig. 2 is a top view. Fig. 3 is a transverse vertical sectiontaken in the line w of Fig. l. Fig. 4 is a transverse vertical sectiontaken in the line y y of Fig. 1. Figs. 5, 6, and 7 are enlarged detailviews.

A represents a base or platform, from which extend upward two standards,al a1, in the upper portions of which is a shaft, F, with its gudgeonsf1 f2 projecting beyond the outer sides ofthe standards. At a suitabledistance from the standards al al are two other standards, a2 a2, in theupper portions of which are arranged two arbors, .Il J2, having gudgeonsjlj2 projecting beyond the outer sides of the standards, the inner endsof the arbors hav ing their bearings in a block located between thestandards a2 a2, so that said arbors are dependent of each other. formbearings for a pair of oscillating beams,

VB1 B1, connected by cord", chains, or bands a similar pair of beams B2,similarly connected by cords, chains, or bands K2. Vhen )k Kl, and thegudgeonsf2 form bearings for E( t motion is applied to either one of thebeams BI or B2, it is transmitted to the other beam bymeans of the cordor chain. The ends of the beams B1 B2 are preferably arc-shaped, so thatthe cords or chains will always maintain arectilineal position. Thebeams of each pair may i The gudgeons f1@ be placed at any `desireddistance apart, and, if necessary, they may be provided withtightening-pulleys for the band, arranged at suitable points betweenthem, when the distance between the beams is such as to cause aslackening ofthe cord or chain. At a suitable distance from the standardal is a standard, c, in

the upper portion of which is journaled a rotating shaft, G1, providedwith a crank at each end, said cranks being at right angles with eachother. One of said cranks is connected by a rod, l1,.with one ofthebeams Bl, and the other crank is` connected by a rod, l2, with one ofthe beams B2. The beams B1 and B2 are arranged on the gudgeonsf1 jl andf2 .72, at an angle of about forty-live degrees with relation to eachother, so that as the cranks on the shaft G1 are atan angle of ninetydegrees with relation to each other the motion transmitted from theshaft C1 to the beams is more uniform, and the shock in passing thedead-points is less than would be the case if the cranks were arrangeddiametrically opposite each other. In order to still further accomplishthe desired object the shaft C1 may be provided with a iiy-wheel. Therods Z1 l2 may connect with the beams Bl B2 at the extreme lower ends ofsaid beams, or at any desired points between the ends and centers ofmotion of the beams. As motion is applied to the shaft C1 it iscommunicated by the rods Z1 Z2 to the beams B1 B2, and through thechains or cords and the other beams of each pair it is transmitted toiany desired distance.

The cords, chains, or bands K1 K2 are passed over the arc-shaped ends ofthe beams B1 B2, and their ends are passed through holes madediametrically in the gudgeonsf1j1f2g2, and' secured by joining themtogether or by knotting them. In either case the cords may bewrappedonce or more around the gudgeons, in order to give it the properpurchase.

To the shaft F is attached one end of a cord, c, which is wound aroundthe shaft and has its other end attached to a spindle, D, arrangedbetween the standards al al. When the cords or chains are first putinplace they are adjusted to the prgpe tension by turning the spindle D,Jre'et of which is to turnl the gudgeons f fland tighten the cords whichare attached thereto.

To the arbors J1 J2 are attached cords h1 h2, which are passed aroundsaid arbors, and have weights G1 G2 attached to the lower ends. Theseweights serve to keep the cords or chains properly stretched, and at thesame time allow for the contraction and expansion of the same, theweights and cords operating to turn the gudgeons through which the endsof the cords or chains K1 K2 are passed. v

Near the end ofthe base or platform A farthest from the standard c isanother standard,

c2, in the upper portion of which is ]'our-naled a rotating shaft, C2,having a crank at each end, said cranks being at right angles to eachother, and connected to the beams B1 B2 by rods m1 m2.

The shaft C2 may be arranged at any desired height above the platform,and the rods may be connected at any suitable points between the endsand the centers of oscillation ofthe beams.

Power may be applied to either one of the shafts C102, and motiontransmitted from the opposite one to the machinery to be driven.

'What I claim as my invention,'and desire` to secure by Letters Patent,is

l. The combination of the reciprocating beams B1 B2, connected by cordsor chains K1 K2, substantially as and for the purpose shown anddescribed.

2. The combination of the rotating shafts C1 G2 with the reciprocatingbeams B1 B2, substantiallyas and for the purpose shown and described.

3. The combination of the spindle D, cords e, and shaft F, substantiallyas and for the purpose shown and described.

4. The independent automatic tightening devices, consisting of theweights G1 G2, cords h1 h2, and arbors J1 J2, arranged and operatingsubstantially as and for the purpose shown and described.
